Golf putting arm guide

ABSTRACT

A golf-putting arm guide has an arm serpentine ( 1 ) that is attached detachably to a top end of a golf-club grip ( 4 ) and articulated to entwine the golfer&#39;s cupward arm ( 8 ) in straightness orientation for acquiring a sense of the straightness orientation to learn putting accuracy. The arm serpentine is preferably a wire having a club-grip end ( 2 ) that fits snugly into a club-grip orifice ( 16 ) in the top end of the golf-club grip. The arm serpentine includes a fore-arm guide ( 7 ) proximate a mid section that fits snugly against an inside of the front or cupward forearm of the golfer. Outwardly from the forearm guide, the arm serpentine includes an arm hook ( 6 ) that hooks onto golfer&#39;s cupward or front arm. The club-grip end can include one or more linear ridges ( 18 ) as anti-rotation fins and a snap ridge ( 17 ) which can be built onto or attachable to the club-grip end of the arm serpentine. The arm serpentine is preferably bendable to fit one arm size or a class of arm sizes rigidly. The arm serpentine can be predeterminedly flexible and have fixable rigidity with ball-and-socket beads ( 21 ) tightened intermediate the arm hook and the club-grip end. Also, the arm serpentine can have structural memory with metallic or non-metallic material.

BACKGROUND OF THE INVENTION

[0001] This invention relates to training devices for golf putting.

[0002] It is well known in golfing that the most accurate putting on a golf green is achieved with a putter head impacting a golf ball perpendicularly to a line of travel of the golf ball to a cup. To maintain reliable perpendicularity, it is preferable that a golfer's lead arm on the golfer's cupward side maintain the perpendicularity. This is accomplished by avoiding any wrist action that would change the perpendicularity and direct the golf ball in a line of travel that would miss the cup. It is preferable also that a putter handle be held like a pendulous extension of the golfer's arms from the golfer's shoulders to the putter head. This allows use of the golfer's body and the putter with mechanical accuracy.

[0003] A problem occurs, however, as a result of a general tendency of people to bend their wrists undetectably and thereby to putt golf balls in lines of travel to sides of golf cups. A feel for maintaining a pendulum motion from the shoulders while holding the putter handle for positioning the putter head perpendicularly to the line of travel to the cup can be learned. Learning can be aided with an arm guide extended from the putter handle to bend-detection contact with the golfer's cupward lead arm. That is the purpose of this invention.

[0004] There are known arm guides for holding golf clubs, but not with an arm serpentine that is attached detachably to a top end of a golf club and articulated to contact the golfer's cupward lead arm for learning effectiveness and convenience in a manner taught by this invention.

[0041] Referring to FIGS. 1-4, a golf-putting arm guide has an arm serpentine 1 which includes a club-grip end 2 and an arm-hook end 3. The club-grip end 2 is attached detachably to a top end of a predetermined golf-club grip 4 that is fixable on a golf club that preferably is a putter 5. The arm-hook end 3 includes an arm hook 6. Included intermediate the club-grip end 2 and the arm-hook end 3 is a forearm guide 7 that is articulated with desired serpentine curvature for positioning against an inside of a golfer's cupward arm 8, which is known also as the golfer's front arm in relationship to putting golf balls. The arm hook 6 is articulated to partially encircle the golfer's cupward arm 8.

[0042] The serpentine curvature of the forearm guide 7 provides a guiding arm-width contact with an inside of the golfer's cupward arm 8 and wrist section. When the golfer aligns a putter head 9 perpendicularly to a line of travel 10 of a golf ball 11 to a cup 12 on a golf green 13 and then putts with a short pushing swing, as depicted by two schematic human figures in FIGS. 1-2, the arm serpentine 1 provides a gentle-touch detection of wrist bend which is to be avoided. Twist or bending of the wrist of the cupward arm 8 tends to cause the putter head 9 to pivot from perpendicularity of the putter head 9 with the line of travel 10. Instead of any wrist-bend action, therefore, the golfer's cupward arm 8 and push arm 14 preferably pivot in unison like a pendulum from the golfer's shoulders 15 without twist or bend of the wrist of the golfer's cupward arm 8.

[0043] This gentle-touch detection for avoidance of wrist-bend action is preferred over more rigid arm guidance or less effective twist detection of previous golf-training devices. The gentle-touch detection allows a golfer to get a feel of wrist rigidity and an undisturbed learning of its cure.

[0044] Preferably, the arm serpentine 1 is a metal rod having a diameter of about one-eighth of an inch and a bent length of about one foot. The metal rod can be bendable to a desired serpentine curvature with or without resilience memory. If resilience memory is employed, the arm serpentine 1 is bent with shop or manufacturing capabilities. If bendable without resilience memory, it can be bent or its bend can be modified by a user. Optionally, the arm serpentine 1 can be a non-metallic material such as plastic that preferably is bent with shop or manufacturing capabilities.

[0045] Reference is made now to FIGS. 1-14 and more particularly to FIGS. 5-14. For its simplest and least-expensive use, the club-grip end 2 of the arm serpentine 1 is inserted into a club-grip orifice 16, shown separately in FIG. 5, in a top of the golf-club grip 4. Insertion of the club-grip end 2 into the club-grip orifice 16 without additional structure of and/or on the club-grip end 2 is depicted in FIGS. 6-7.

[0046] Shown in FIG. 8, a snap ridge 17 is added proximate a tip of the club-grip end 2 for preventing its removal from the club-grip orifice 16 without predetermined pulling of the arm serpentine 1.

[0047] Shown in FIG. 9, at least one linear ridge 18 is added proximate the tip of the club-grip end 2 for preventing rotational twisting of the club-grip end 2 in the club-grip orifice 16 predeterminedly.

[0048] Shown in FIG. 10, the snap ridge 17 and the at least one linear ridge 18 in combination are added.

[0049] Shown in FIGS. 11-12, an attachment base 19 is added for convenience of grasping the club-grip end 2 of an arm serpentine 1 that can have a smaller diameter for bending ease on a club-grip end 2 that is sized and shaped for snug-fit insertion into the club-grip orifice 16. The attachment base 19 can be employed in combination with or without the snap ridge 17 and/or the linear ridge 18.

[0050] Shown in FIGS. 13-14, 16-17 and 25, a clamp 20 can be added for grasping top ends of the golf-club grip 4 to achieve additional attachment rigidity, particularly for embodiments having shape-adjustment features of the arm serpentine 1. The clamp 20 can be a simple spring type as shown or can include fastener features.

[0051] Shown in FIGS. 15-19, 21 and 23-25, the arm serpentine is bendable and fixable in a desired bent shape with a plurality of ball-and-socket members that are preferably ball-and-socket beads 21 having line orifices 22 intermediate ball sides 23 and socket sides 24 that are oppositely disposed.

[0052] The ball-and-socket members which are shown as being spherical and referred to as ball-and-socket beads 21 can be any shape, mixture of shapes or plurality of shapes which have the line orifices 22 intermediate ball sides 23 and socket sides 24 that match with the ball sides 23 fitting pivotally inside of the socket sides 24, regardless of whatever shape or shapes other portions of separate ball-and-socket members or ball-and-socket beads 21 have. Spherical ball-and-socket beads 21 are depicted for ease of illustration and possibly popular shape. Rectangular, figurine, wafer, oval and irregular forms are foreseeable.

[0053] The ball-and-socket beads 21 are strung juxtaposed on the arm serpentine 1, the arm serpentine 1 having a predetermined diameter and flexibility being inserted through the line orifices 22 sequentially with the ball sides 23 being positioned in the socket sides 24 of adjacent ball-and-socket beads 21 intermediate the club-grip end 2 and the arm-hook end 3. The arm serpentine 1 includes a joint tightener for tightening the ball sides 23 against the socket sides 24 of the ball-and-socket beads 21 for rigidity of select shaping of the arm serpentine 1.

[0054] The line orifices 22 have entrances with inside diameters sufficiently large to allow predetermined rotation of the ball sides 23 in the socket sides 24 universally without restriction by encountering the arm serpentine 1 on which the ball-and-socket beads 21 are strung.

[0055] The joint tightener can include a joint tensioner or a line tensioner for providing rigidity-tension pressure of the ball sides 23 against the socket sides 24 of the adjacent ball-and-socket beads 21 intermediate the attachment base 19 and the arm-hook end 3 of the arm serpentine 1.

[0056] Shown in FIGS. 21-22, joint tensioners can include at least one tightener wedge 25 that is forcible intermediate a terminal-end ball-and-socket bead 21 and the attachment base 19.

[0057] Shown in FIGS. 19-20, joint tensioners can include at least one wafer spring 26 having joint-tightening pressure intermediate two or more adjacent ball-and-socket beads 21.

[0058] Shown in FIGS. 23-24, joint tensioners can include a double-nut tensioner with the arm-hook end 3 of the arm serpentine 1 attached to a terminal bolt 27 on which an adjustment nut 28 is screwed against preferably an end plate 29 or other bead protection at the arm-hook end 3. As shown in FIG. 24, the terminal bolt 27 can have a rounded socket head 30 and the adjustment nut 28 can be a finger nut 31 with a prong-wrench orifice 32.

[0059] Shown in FIGS. 17 and 25-27, the line tensioner 33 can include a cam axle 34 with an eccentric projection 35 rotatable against a line anchor 36 that is positioned proximate an opposite side of a cam-axle housing 37 from the arm serpentine 1. A hand lever 38 is attached to the cam axle 34. The cam-axle housing 37 is positioned on the attachment base 19 and the arm-hook end 3 of the arm serpentine 1 is secured to a terminal ball-and-socket bead 21. The cam axle 34 is provided with a line orifice, a line channel or end portion as represented by a channel ridge 39 for passage of the arm serpentine 1 from a bead side to a base side of the cam axle 34.

[0060] The arm-hook end 3 of the arm serpentine 1 is attachable to a line plug 40 or to a terminal ball-and-socket member in opposition to tightening pressure of the joint tensioners or the line tensioners 33.

[0061] Tightening pressure in relationship to slide resistance of the ball sides 23 in the socket sides 24 can be provided by a combined resilience of the arm serpentine 1 and the ball-and-socket beads 21 sufficiently to require only occasional tightness adjustment for temperature, moisture and wear factors that change tensional slide resistance. Predetermined slide resistance surfacing or inserts can be employed between the ball-and-socket beads 21.

[0062] Spherical circumference of spherical ball-and-socket beads 21 is preferably about one quarter of an inch, but can be larger or smaller as desired by users.

[0063] Coloration of the ball-and-socket beads 21 can be employed for attractiveness and for identification factors.

[0064] The golf-club grip 4 for most putters 5 has a cross section that is somewhat egg-shaped as shown in FIGS. 5-6 and 14. This helps an experienced and talented golfer to prevent pivoting of the putter 5 from perpendicularity of the putter head 9 and the line of travel 10. Oppositely for less-talented golfers, this egg shape can accentuate a pivoting or wrist-twist problem. This invention provides gentle-touch learning for preventing wrist twist like a talented golfer.

[0065] These advantages can be provided with the simplest wire embodiment or with levels of sophisticated embodiments with wide variation of attractiveness and adjustment of gentle-tough effectiveness to desires and needs of golfers.

[0066] Referring further to FIGS. 7-12, 15 and 17, the arm serpentine 1 can be extended into a hollow top end of an inside periphery of the putter 5. There, it can have an anchoring curvature 41 that buttresses against one or both inside peripheries of putter 5. The golf-club grip 4 of most conventional putters 5 and other golf clubs have orifices or can be provided with orifices through which the anchoring curvature on the arm serpentine 1 can be inserted. The golf-club grips 4 also are generally resilient with at least a partially rubberlike characteristic. This provides a resilience that can be employed in opposition to the anchoring curvature 41 for desirable tightness of fit and rigidity of the arm serpentine 1, regardless of whether the anchoring curvature 41 is buttressed intermediate either or both oppositely disposed side walls of the inside periphery of the putter 5 and a side wall of the orifice in the top end of the golf-club grip.

[0067] The anchoring curvature is particularly advantageous for arm serpentines 1 having adjustment features and not having clamps 20.

[0068] A new and useful golf-putting arm guide having been described, all such foreseeable modifications, adaptations, substitutions of equivalents, mathematical possibilities of combinations of parts, pluralities of parts, applications and forms thereof as described by the following claims and not precluded by prior art are included in this invention.
